Specification of Letters Patent.

Patented June27, 1922.

Application filed August 9, 1920. Serial No. 402,132.

To all whom it may concern Be it known that I, MATHiAs HAUPT, a

citizen of the United States, residing at Roscoe, in the county of Stearns and State of lvlinnesota have invented new and useful Improvements in Snowplows, of whlch the following is a specification.

This invention relates to a snow plow for use on streets and roads and the principal object of the invention is to provide a frame which carries conveying means and shoveling means and means for conveying the snow from the shoveling means on to the conveying means.

Another object of the invention 1S to provide reciprocating shovels for shoveling the snow off the street.

This invention also consists in certaln other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like oh. racters denote like or corresponding parts throughout the several views, and in which Figure 1 is a view of one side of the mvention.

Figure 2 is a view of the other side.

Figure 3 is a plan view.

Figure 4 is a longitudinal sectional view.

Figure 5 is a cross section on line 55 of Figure 3.

Figure 6 is a bottom plan view of the front portion of the apparatus.

In these views 1 indicates the frame of the apparatus which is shown as provided with the runners 2 on its lower edges, through it will of course be understood that it may be mounted on wheels. The upper part of the frame extends upwardly at an incline from the pointed front end and is of channel construction. In the front end of this channel is arranged the shoveling means which comprises a series of shovel strips 3 arranged parallel to each other and mounted for reoiprocatory movement in the cross pieces 4: forming part of the frame. As shown each shovel strip is provided with an overlapping part 5 which overlaps to an edge of the adjacent shovel strip. A crank shaft 6 is j ournaled in the lower part of the frame and its cranks are connected with the lower faces of the shovel strips by means of the connectmg rods 7 so that as the crank shaft is rotated the shovel strips will be moved backand forth! The cranks are so arranged that when alternate strips are being moved in one direction the remaining strips are being moved in an opposite direction.

An endless conveyor is carried by the rollers 9 mounted in the rear part of the channel and a curved cross piece 10 is placed between the rear ends of the shovel strips and the forward end of the conveyor. In order to force the snow from the shovels on to the conveyor and across the strip I provide a reel 11 which has its shaft journaled in the arms 12 which are connected with the frame.

The arms of the reel are provided'with the blades 13 which push the snow from the shovels across strip 10 on to the conveyor and said conveyor will carry it upwardly to the rear end of the frame and will discharge it into a chute 14 which will carry it to a dump wagon or the like.

The crank shaft has one end extending through the frame and this end is provided with a pulley 15 and this pulley is connected by the belt or chain 16 with a pulley 17 secured to the end of the shaft of the lower roller 9 and the other end of this shaft is provided with a pulley 18 which is connected with a pulley 19 by a belt 20, the pulley 19 being carried by a shaft 21 which has a pulley 22 on its other end to receive a belt 23 which passes over a pulley 24: on the end of the shaft of the reel. The shaft 21 may be driven in any desired manner. For instance, it may be driven by a motor carried by the frame or it may be driven from a movable part on the truck or other vehicle which is used to push the snow plow along.

It will thus be seen that when the apparatus is being used the reciprocating shovel strips will scrape the snow and ice off the road surface and this snow and ice will be carried to the conveyor by means of the blades on the reel. The conveyor will carry the snow and ice upwardly and deposit it in the chute which will convey it to the road or into a wagon. The shovel means will act to loosen frozen snow and'ioe. By having them overlap the snow is prevented from dropping between the strips.

It is thought from the foregoing description that the advantages and novel features I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall with: in the scope of the appended claims;

l/Vhat I claim is 1. An apparatus of the class described comprising a supporting frame, vhaving an,

upwardly andrearwardly extending channel part, shovel means in the lower part of said channel part comprising parallel strips and means for reciprocating the strips and concomprising shovel strips and means for re ciprocating said strips, said means moving alternate strips forwardly while the remaining strips move rearwardly.

4. A snow plow of the class described comprising a frame having a channel in its upper part extending upwardly and rearwardly from the front end, shovel strips located in the front part of the channel, means for reciprocating said strips, conveyor means in the upper part of the said channel, across strip located between the shovel means and the conveyormeans, a. reel, blades supported thereby and means for rotating the reel'to cause its blades to push thesnow across the cross piece from the shovel means on to the conveyor means.

In testimony whereof I affiX my signature.
